Coyolxauhqui is the Aztec Moon goddess. Her name means "Woman With Copper Bells on Her Cheeks", and when the moon rises full and red you can still see them.

Her mother, Coatlicue, became magically pregnant when a crown of feathers fell in Her lap. Believing Her family had been dishonoured, the angry Coyolxauhqui meant to kill Her; but the child Huitzilopochtli, whose name means "Hummingbird on the Left" (the south, i.e. the Sun), springing from the womb fully armored, defended Their mother and killed Coyolxauhqui instead. He cut off her head and flung it into the sky, where it became the Moon.

The combat between Coyolxauhqui the Moon and Huitzilopochtli the Sun represents the alternation of day and night.

Coyolxauhqui on a pragmatic level can indicate sibling rivalry. On a larger level, this card represents transcending differences and being able to move the spirit to a higher plane.
